Shodoshima
An Inland Sea island of olive groves and soy sauce sheds, with a sandbar that surfaces twice a day.
Updated 20 October 2026
Shodoshima is the second largest island in the Seto Inland Sea and grows olives - the first successful commercial planting in Japan, from 1908, when the government trialled several sites and only this one took. The groves are still there and the island sells oil, cosmetics and olive-fed beef on the back of it. The other industry is older: soy sauce has been brewed here for four centuries in wooden barrels in cedar-boarded sheds, and a cluster of working breweries around Hishio no Sato can be walked through, with the smell hanging over the whole district. Angel Road is a tombolo linking small islets, exposed for a few hours around low tide and submerged the rest of the time. Kankakei, a gorge on the island's interior, has a ropeway and is one of the better autumn colour sites in western Japan.
History
Once known as Azuki-shima, the island belonged to Kibi, later Bizen, Province, was then given to Sanuki Province and finally became part of Kagawa Prefecture; it was the first place in Japan to grow olives successfully and is the setting of the novel Twenty-Four Eyes (Wikipedia, Shōdoshima).
Highlights
- Olive groves - the first commercially successful planting in Japan, from 1908.
- Soy sauce sheds - four centuries of barrel brewing in cedar-boarded buildings.
- Angel Road - a tombolo walkable for a few hours around low tide.
- Kankakei gorge - a ropeway and strong autumn colour in the island's interior.
When to go
March to November; November for Kankakei. Two days. Check the tide for Angel Road.
Good to know
The island is large and buses are infrequent - a car or scooter makes a real difference. Angel Road is submerged most of the day and the timing must be planned. Ferries are weather-dependent. Peak triennale years bring heavy crowds.
Nearby
Teshima and Naoshima are west across the Inland Sea; Takamatsu is south.
